We do have the same issue and it is related also to earlier versions of TA.

I only came across this issue, when I could work with an assistant. With an assistant I can switch on the controller, before he is finished with the setup of the station. Only than I had this issue. Understanding this I found the following work around:

Set up the station and wait until the station is ready to connect (shows radio channel and network ID). Only then switch on the controller with TA. This error can be reproduced most of the time by switching on the controller first.

Peter's copy and paste of my comments to him on this don't seem to have come through, so here's what I said:

Hi Peter,

Not an awful lot was changed in 2017.10, so I doubt 2017.10 is working any differently to 2017.00 in this regard.

I don't run robotic survey's often, so I'm not much of an expert in this area, but I'm not aware of any issues like this, so I'd suggest you work with your distributor and see if they can help track down what the problem might be here.

Thanks for the enhancement suggest, we have a few naming threads, and this option is only working on one - but at some stage when time permits I would like to improve this, so I'll keep this suggestion in mind for then.

Cheers

Rob

Until very recently we've not had any reports of this issue coming in through Support, so we've had nothing to investigate. We have had some reports very recently, and are trying to get more information to see if we can understand what is going on here, I'm hoping we'll have something to look at soon.

Replying to the questions about Auto connect to the Focus 30/35. In general if you never use this switch it off, that said, we did time test to S Series instruments with just the S Series enabled, as well as the Focus, and in all our testing it took up to about 15 seconds in all cases, regardless of whether Focus was on or off. If it's taking more than 20 seconds, then we'd love to get some comms traffic to analyse so we can understand what is going on. Again, the best people to work with on this are your distributors.

In the recent version of TA 2017.00 the Spectra Precision Focus30/35 robots were added. With this addition they was a check box added for them under settings/connect/auto connect. By default TA has all boxes checked. You will need to uncheck the Focus30/35 box. You may want to uncheck the 5600 box as well if you are only using S-Series instruments. This should help improve communication/connection times.

Rob, I am a Geospatial sales and Tech support rep with Seiler Instrument, a Trimble distributor in the US, and would be happy to discuss some of our findings regarding this issue. This has resolved the problem with several of our customers.

There was a Service Bulletin about the radio module...If you have version G, K, Q and has 5.58 firmware then you maybe entitled for a warranty repair. You can bring your TSC3 to a service provider and have the module check.

I thought I had damaged the original TSC3 antenna, thought it couldn't be the S6 as it had just had annual service with no communications issues reported. Purchased latest antenna, replaced & completed job with no more dropouts.
